i started getting smoke out of my exhaust on r32 gtr so i was adviced it was probably a turbo seal gone.
so i replaced both turbos got it all back together and still smoking away! what could it be? anybody?:runaway:

 

[alex2005]

breathers??

 

[trevbwhite]

being a novice mate i dont really know what to look for! on idle a bit of smoke can be seen by the manifold when it warms up but thats it if u drive it then it comes out the exhaust but dosent when it is on the drive idling

What colour? Blue, white or black?

 

[trevbwhite]

What colour? Blue, white or black?

White. Smoke mate

 

[ANDY H]

it could be oil left in the exhaust from the first set of turbos!

 

[trevbwhite]

I don't know mate seems a lot of smoke only seems to come on with boost and I changed the downpipe. Will chech plugs 2mora to see if there's any sign of oil in them! But there is smoke from round by both turbo's in the engine bay

 

[ANDY H]

thats not a good sign! whats the history with the turbos?

 

[trevbwhite]

Not sure of the history of them fella got the from rk tuning the other day are used ones. Was smoking the same on old ones I thought swapping them might solve it.

 

[trevbwhite]

There used ones I got from rk the other day may have to pull them off check everything is on right?

White smoke suggests it's water fwiw (blue = oil, black = unburnt fuel)

 

[trevbwhite]

oh right thats interesting cos i just had a water leak fixed a few weeks before this happend! maybe summin to do with that?

 

[ru']

Well, white smoke suggests water being burnt rather than just leaking, i.e. possibly head gasket for example. Where was the leak?

Does it smoke continuously when driving, or just when accelerating, or just on the overrun etc.?

 

[trevbwhite]

well my water temp dosent move to be honest. there is nothing in the coolant and i snif tested the block the other day and it all came back ok
its more overrun it smokes at

 

[freakazoid3]

White is water as suggested above already. If it's smoking it's worst when in overrun I would do a leakdown test to see if the headgasket went.
That would be my first bet.
If not perhaps a cracked block...? Does she use water?

 

[trevbwhite]

nah not using water (not enough to notice) has just started!
have done a sniff test and that has come back fine
may do it again just to be on the safe side!

 

[ru']

iirc smoking on overrun may possibly be valve stem seals? Obviosuly that'd be oil smoke, not water.

 

[freakazoid3]

If the whie smoke goes away after some driving, it may well be condensation in the exhaust itself. Some pipes collect a lot to blow it all out again when you start her up after being standstill for a while. So let her warm up and see if the smoke goes away

 

[trevbwhite]

Smoke dosent seem to go away sadly also heard it could be a connection in the intercooler pipework?

 

[ru']

Leaking intercooler pipework usually results in black smoke due to running way too rich.
